Is there one?

I've used Clipboard H+S off and an for years now, and have always been impressed by it.  The main reason I keep straying away from it is because I really need something that can let me easily access my clips whether at home or at work.   i.e. Is Dropbox-friendly.  If it was portable, I could (?) "install" it in my Dropbox folder, then it wouldn't know which computer I was on.  I would just need to make sure I didn't have both computer running at the same time.  I've been doing this successfully with the portable version of ClipMate.  Unfortunately, ClipMate seems like it might be abandonware now.  Plus I want to use CHS simply because I have a vested interest in DonationCoder.  (And CHS has a better quickpaste menu.)

The new Ethervane Echo seems to handle the dropbox issue pretty well.  I like CHS better though, because it handles pics (and for a couple other reasons; Though Echo is awesome in it's own right).

I'm surprised that searching the CHS board for "dropbox" yields zero results.  Surly I'm not the first person to think of this. 

Extra notes: I know I can export when shutting down, then import when I start the other computer, but I don't really  consider this a viable option (I"m just too darn lazy!)  Also, having a list of friends on a network and network passwords, etc etc like Ditto is overkill IMHO.  It would be okay if it could monitor for any changes in the database, but mostly I just need the portable bit.

Thoughts?  Comments?  Thanks.
