"It's much more than a simple bookmark storage, the RFC remarks:
The Application Configuration Access Protocol (ACAP) is designed to support remote storage and access of program option, configuration and preference information.
Probably the main reason this isn't being used is because you can't rely on every user having access to an ACAP server. Well, why not have both? Your browser could implement a mini-server until you find one that you can use. So should I suggest this to Mozilla/Microsoft/Opera? Or is there a simpler way. When Netscape was the king, I simply uploaded the bookmark file to my homepage area, it worked (more or less). And since I use browser 90% for content not on my computer I'm very likely to have net access when I'm using my browser. So could this be feasable, or am I daydreaming again?"
