Don Park [Don Park's Blog] joins in about Universal Personal Proxy and opines that IBM Sash is almost exactly what they are talking about.
First, I don't think that's at all what they are talking about - to me the UPP discussion has been about a proxy that sits in on all your 'conversations' on the web, filtering, analysing, categorising, agent based recommendations etc. Indeed this is not a new idea but is not what Sash is for, but then he goes on:
It has a cool IDE for writing weblications. There is even a Linux port of Sash. What really intrigues me is why it hasn't taken off.
Indeed. He has an idea:
One has to download a large toolkit and myriads of extensions. Web developers need only a text editor and a FTP client.
Well, Zeepe is small (approx 260K), does an aweful lot of what Sash does and (ahem) needs only a text editor and FTP Client.
