What are the requirements and application process for a DTV visa at the embassy in Lisbon?

Does anyone have experience of applying for a DTV at the embassy in Lisbon? If not, can I ask for tips on how best to find out the requirements of specific embassies? (I now have the 500,000 baht but am wondering for how long Lisbon will expect to see it sitting in my bank account.)

Also, is it necessary for me to apply in Lisbon because I happen to be here at the moment? Or could one apply anywhere else (other than in Thailand itself)? Part of me would like to get on a plane asap and go out to South East Asia rather than waiting around here.
