John, have you posed this same question to the TTG forum? Matthew and Rod are usually quick to respond.
I could've sworn I was able to publish multiple albums by flagging several to republish & then clicking on the Lightroom Publish button at the bottom left of the screen. But your question has me wondering --- will try it again.

Yes, I did post on the Backlight forum and got an answer: Here's the link:

"Regarding publishing more than one album at a time......
"Lightroom will allow it. All you have to do is go to each album and click on publish and it will start multiple publishing streams. However, don't do it!!! Either Lightroom of Backlight (not really sure which) can't handle it, and you will end up with messed up galleries on your site. Some of the things you'll see are captions missing and photos out of order. It's easy to fix, but a waste of time.
"There is one way that does work, but it won't apply in all circumstances. If you have a collection/album set defined in the publisher interface. you can click on it (bringing up the display of all the photos in the set), and then click on Publish, and it will work it's way through everything in the albums in that set that needs to be published. Since that does them one at a time, things don't get screwed up."
What I found is that if I place several collections into a collection set, I can then select the set to publish and then all images within that set are published.
