The outsourcing of drafting is a tough situation. You can definitely get some economy through cheaper labour, but my experience (been through this three times) is that you typically get people that just "Draw pictures" without putting any actual thought into what's happening.
Realted, I think most people would agree that the biggest challenge with our multicultural teams in Calgary is communication. ESL is a fact of life and working in a team filled with different accents and linguistic capabilities can get tough. Still, its way easier when everyone is in a room together and you can use sketches (and such) to ensure alignment. Having 3 or 4 different accents on a telephone call is a brutal way to get things done, adding in ungodly hours due to time zone only compounds the problems.
In the end, based on my experience anyhow, outsourcing looks good on paper until you inevitably find yourself forced into design changes at a late stage because of it. Its a huge PITA and ends up eating all of your perceived savings.
