Is iGoogle the next SharePoint?

Could iGoogle be used as an effec­tive alter­na­tive for the Microsoft col­lab­o­ra­tion tool Share­Point?  Let me qual­ify that by say­ing, I don’t mean today — but rather in the not so dis­tant future.  Share­Point is a pretty pow­er­ful appli­ca­tion.  Still, if you look at what Google is try­ing to accom­plish with web based appli­ca­tions and cloud com­put­ing, ask your­self “could iGoogle be devel­oped into a fairly robust col­lab­o­ra­tion tool.“  It already allows for cus­tomiza­tion of con­tent, and there are numer­ous gad­gets that deliver every­thing from email and cal­en­dar to ToDo lists and games.  You can also share indi­vid­ual tabs with oth­ers — allow­ing for a shared work­space for small teams.  I have been pon­der­ing this for some time, and thought I would put it out there for dis­cus­sion.  While I think it is a long way from being some­thing that could be rolled out in a large firm, small busi­nesses could absolutely uti­lize this free tool to com­mu­ni­cate with cus­tomers and employ­ees alike.  Also, the fact that Share­Point is one of Microsoft’s hottest prod­ucts, must make it a huge tar­get for com­pa­nies like Google and oth­ers.  You have to think that the peo­ple at Google have at least pon­dered this notion.  So, what do you think?  Could you use iGoogle as an effec­tive col­lab­o­ra­tion tool?
