Advice for music outdoors

OK, so I'm going to be installing some outdoor speakers for tunes in the backyard. I've got the speakers part covered, but what do others do for electronics?

I'm thinking of locating an integrated amp in a closet near the door to the deck, with an iPod hookup and a CD player. Speaker cables would end up about 25' long, with the speakers mounted to the house. For the most part, people will face away from the house with the sound coming from behind, and of course will also be moving around, talking, etc.

I want 'good' sound, but it doesn't have to be great sound. I was thinking of the lower end Arcam, Rotel, Cambridge audio, etc, stuff. It seems like spending more money would be wasted due to the long speaker cables and non-ideal listening environment - but I'd like to hear the experiences of others.

Another question is on the remote, is there any practical way to have remote control from outside (where the kids may occasionally leave the remote - rain, etc). An RF setup with a weatherproof remote would be good, but not sure if that exists.

So, has anyone 'been there, done that' and have any advice they could offer?

Thanks!
