It uses the split command to create a single page view that's got
yubnub.org (with cmdline) gmail, mundu (multi protocol IM),  espn,
google reader, and dropbox   each optimized for the iphone screen.

or go to yubnub.org and type: Split {url cmd} {url gmi} {url mun} {url
mspn} {url mgr} {url idrop}
and enjoy. The yubnub frame and cmdline  is to allow "web surfing"
within the multitasking single page. If you want to go back within
that one frame type ":h" on the cmdline and it will list a history.

That's the UPSIDE. I realize the split command was made more for
searching multiple sites at once than for an ongoing multitasking
action... and that given that yubnub.org goes down from time to time
and that this must put more strain on yubnub's servers since they host
the whole thing that this might be too much...

BUT there's some real potential here. It's definately beta-ey and
potential mostly. But how else can someone on an un-jailbroken iphone
read RSS while chatting, casually surfing the web, checking sports
scores, and emailing all at once, all without home-buttoning their way
in and out of applications, signing in, signing out, etc etc....

you can even do a Pink Floyd album cover type trick of (using the
above example page) typing another Split set into the cmd line... web
views within web views  etc...

I can do some html and javascript, but I don't know if I can improve
on the split command itself by myself. Ideally this implementation
would have a way of going back in the history of a split frame without
using the cmdline hack  and even better would have a way of entering a
new url in a single split frame.

Any thoughts? Is this beyond the scope of yubnub? I can't find any
mention of this use anywhere on the web. But it can be useful. I think
the existing implementation of "tabs" in a mobile browser is wrong. It
is carried over too directly from PC browsing. Better than tabs is
multiple frames in a single view that you can scroll over to. And here
it's already mostly implemented...
