No, praise whatever god/being works for you, I don't have a day job. 
I've been oh so happily semi retired for over seven years. (NO, I didn't 
wait for 65 - praise, etc. again.) Having the time for the fun of 
getting back into photography with both feet has been great.

I do a little consulting for my former employer, where I was wise/lucky 
enough to design some small, but important, computer systems. One of 
them is deeply embedded with the top executives of a Fortune 500 
company. And I'm the only one who knows it's insides. Yup, even the big 
boys sometimes breed skunk works. So my income has been and will be, at 
least for a while, enhanced by that, as changes and enhancements are 
desired. I start work on another nice little revision project tomorrow.

So far, the only material reward my unbelievably sage and useful 
advice/help here ;-)   has netted me is a few bottles of lovely brew 
from New England. No complaints, though, either about the excellent ale, 
its excellent sender or the lack of other spiffs. I do it for my own 
purposes.  If anyone should feel compelled to donate, I wouldn't turn it 
down, and would probably be gleeful at the very idea - this address is a 
PayPal address. :-)

Really, if anything you read from me here is worth more than you paid 
for it, enjoy! Pass on whatever you have to pass on to someone else. If 
we were all passing on what we have to offer more freely (and with fewer 
strings and expectations), we'd all be richer in the things that count.....

It's a shame Lightroom doesn't have plug-in capability yet. It's going 
to be a while, and will require each one to be especially 
written/interfaced for it. PS plug-ins likely won't ever work in Lightroom.

It's simple for a PS user like me. PTLens is just another filter that 
can be included in Actions (macros). The several images I did of yours 
took less time than you might imagine - open, click on an action, take a 
few seconds to see what it did (layers again!), and save. Then grab the 
originals and results, drag into JAlbum and bang, web gallery. The 
looking at results part was only because I didn't have the focal length 
info. Otherwise, one may run it as a batch.

The standalone version of PTLens will intelligently batch process 
images, applying the appropriate profile based on lens and focal length 
data in the EXIF. On the down side, the stand-alone version doesn't 
handle RAW and TIFF images or 16 bits. (I guess the plug-in in effect 
inherits those capabilities from PS.) So for you, PTLens batch 
processing would be an after Post affair

I don't know. I tried the Beta,and Lightroom just isn't the tool for me, 
so I passed on the $ version. It did some stuff easier or cooler than 
PS, but didn't do other stuff I absolutely rely on at all. I seem to be 
a layers and masks sort of fellow, among other things.

As far as I could find out, the only thing that comes close to PTLens 
for working automatically with profiles, rather than hand work doing the 
correction, is DxO, for many more $$. I've even used PTLens with good 
results for non-profiled old MF lenses by rying profiles for other lense 
of similar focal length til I find one that works. Maybe not perfect, 
but better than the alternative. Especially so when working with an 
image with no straight lines.
