Any way to memory in mobile devices?

Hi

I've been working with funambol for a couple of weeks now and integrated 
it with some systems that I and my company use. It is starting to look 
good and I like funambol, but we have one problem though.

Most people have a lot of calendar items from years gone by and they 
want to save those items in their outlook (or other app's) calendar. 
They also want their cellphone's calendar to be in sync with their 
outlook. Problem is that when you sync somewhere around 2000 items to 
some phones, the memory kinda fills up. So my question is:

Is there a way to only sync items newer than todays date to some 
clients? Or is there some other rule that can be used?

If there is no existing function, can anyone point me some place in the 
source where I can implement this? I have been looking around in the 
repos, but have not been able to locate any function like this. I tried 
to hack the outlook plugin to only output new stuff, but I got server 
errors when I tried it and I cannot figure out how to fix that.

Thanks alot.

/Johan
