ZenZui is now an equally silly-named Mobile Start-Up, called Zumobi. Ah, that name's much better. Riiiight...
Anyway, they use Java ME technology to serve up tiles of content instead of using the traditional WAP Web browser to go looking for content on the cell phone.

ZenZui now Zumobi
Here's a quote:
Zumobi takes accessing, retrieving,
and sharing Web-based content
beyond traditional mobile
browsers... [t]hrough... "Tiles".
Cool. Now can they tile my hall bathroom with Java ME MIDlets? I'd like that. :-)
