Redmine hosted for free?

Hi everybody,

Absolute beginner with redmine. I would like to know (I haven't found the information anywhere) IF REDMINE HOSTED SERVICE (NOW APPARENTLY FREE) IS INTENDED TO BE FOR EVER, no matter how many project or people is involved. If there is a caveat, I would also k¡like to know where may I find a commercial hosted Redmine Saas.

Thanks very much,
