Instead of Maptools, I reccomend using D20Pro. Works way better. And their programmers support it way better.
heres a link to my Projector Table:

nice huh.....i got shoved to the basement for my Man-Cave. Its cool though, if people are late we play Pool or belly up to the bar for some "Libations". hehehe.
That is a cool table, job well done.
My group has been experimenting with technology as well.
First, we tried a projector suspended over the table, with maptools, pretty cool.
Then added the wii-mote IR Pen trick. Better.
Then we got a much better projector and I looked into building a multi-touch table. While playing with the projector, I opted to shoot it at the wall, guess what, the wall is the best option for my group.
We added a second laptop to be the maptools client, and gave it a wireless mouse. Now my players pass the mouse around and control their characters.
Using the wall has freed up a ton of space on the table and allowed us to present a much larger map. Even the guy with bad eyes can see it. No need for minis since we just use the maptool's tokens. This works for my group and it works great for the guy who travels.
