I've done a lot of work on this. Depends on how much functionality you 
want. TMS, Image work fine. The moment you get into queries and vectors, 
it gets tough. WFS is out.  Chrome is hopeless. Its security model wont 
let you use ajax so its a real struggle to get KML,GML (your only vector 
options) in. You have to make heavy use of tag injection to get JSON in. 
Other browsers are okay with KML/GML but they need to be small as they 
are slow to load. you might like to look at
