I recall there was an effort by some that would force Reps and Senators to spend more time in their districts/states. Vote electronically.
Heck, getting out of their districts is half the reason some of these guys run. (I think that is why there are so many closeted gay Republicans from Red States.)
In 2013, there is little reason to have congress meet in DC. Everything should be done openly and electronically. With few exceptions, just about everything could be done remotely. Keep DC around for swearing in, SOTU, and other assorted ceremonies, but not much more than that.
Even a lot of stuff that is routinely done behind closed doors could be opened up. Secrecy is the bane of a Republic, and should be strictly limited to where it absolutely cannot be avoided. Every single document produced should be available immediately online without exception. THOMAS does a pretty good job of this, but much more needs to be done routinely.
