I have been doing some testing with the E2500 unit... I think the port is going to be pretty easy. I will attach some output dumps from the e2500 that I conducted during my testing.... Today I noticed that walmart/staples/officedepot are no longer carrying the E2K/E3K/ and are moving to the E1500/1700/2500/4200. So porting to E2500 is not a bad idea...
