Trying to limit the amount of money on the table?

[whodaman]

I play in a few different home games.
Last night we played .25, .25 blinds and there were five of us playing. Most people bought in for 10-15$ and quickly rebought two or even three times. Soon there is over 140$ on the table and no one wants to raise the blinds or buy chips off eachother.
Most of the time having lots of money on the table is good for me, but when im having a bad night it can lead to huge downswings which my bankroll really doesn't like.
My question is how to get my friends to limit the amount each of us is buying in for?
1. Buy the chips off each other or buy some % of the chips?
Problem is that the guys like being deepstacked.
2. Adjust the blinds somehow?
Reason is people start playing ridiculoousy tight by the end and the game gets boring when we have 2 guys who have 4 $ in chips and 2 guys with 60+
3. Don't let people rebuy more than x number of times?
Problem: There my friends and if they want to play(and give me there money) I'm not going to kick them out etc..
4. In hellmuth's book he says to have people cash out chips above a certain amount... I dont see how this would help tho?
Any suggestions as to how I can keep my 10$ buyin game with 5 friends from turning into friends losing 50$ a night?

Thanks
Mike
