Is there any way to syncronize / replicate the Treo memo pad over the air with some service that then lets you look at / edit your memos via a web site, and then sync those changes back?

A treo app other than the memo pad that serves the same purpose would be fine too.

Alternatively, is there any free/open source software I could run on an internet-connected computer that would allow me to sync my memos with that computer (with or without a web interface)?

Thanks,
