A good test would be to set up a bookmark resource page in many of these tools, and then share the public url. With a few categories and notes on some of the bookmarks, when possible. Mulitple tabbed (or linked in some way) pages would be a nice test too (e.g. can you move from one page to another a whole group?)
Papaly does allow an invite by email and your own workcenter can mix public and private. The concern is that they recently had a contraction, the future may not be as vibrant as the past, but they do seem to be one of the best (Draggo and a couple of others that look good I have not compared, I probably have a few to add on my next post, one listed its competitors.)
Also what is the quickest method to set up? Some of these tools like Papaly have a Firefox extension for drag and drop, but I find it might be quicker to work with cut-and-paste of the url and creating a new entry.
In general, the quickest personal way is to use Roomy Bookmarks on Firefox and drop one after another into a folder. A similar method involves Onetab, but that is less navigable. An interesting question would be quickly setting up a section in a bookmark folder, then opening up all those urls on one page, and then importing them into the preferred tool above. Economy of movement.
I'll plan on setting up a Papaly page. Xerpi is one not mentioned, but it is somewhat dormant, its plus is that you can fit much more on a page and, like Papaly (and many others) has the ability to move around individual urls and and groups by drag and drop. However, since I could not find a way to change passwords, I can not recommend Xerpi.
My search was more from the perspective of start pages as well as bookmarks. So that includes start.me, Netvibes, Symbaloo, Protopages, Ighome, etc.
