Just did some googling and I couldn't find any info about SPV clients for litecoin so we might be out of luck on that one. Every search I tried turned litecoin into bitcoin when asking about SPV 
Ah, that's what I figured. If they get their act together and decide to implement some form of SPV support server-side, the client side shouldn't be that much work (but like I said, I don't know much about altcoins, so I may well be missing a big chunk of work).

Yeah, it was a long shot. I suppose if litecoin had SPV support other clients would have integrated it by now. Concentrating solely on bitcoin is fine since you are developing a wallet with a different "flavour". Can't wait to try it out on my Mac. When do you think it be ready for a spin?
