I agree. I'd pay for this functionality, also. I carry two phones a lot of the time just for this. A simple way to just view my lists/perspectives on the web would satisfy my needs. I don't necessarily need to manage everything via the web, just get at my data (and maybe a quick entry to dump into the inbox though that can be done via email, etc)
With Omni Sync Server already there it seems like the data portion isn't a problem. Just querying it and rendering it in a mobile readable form.
I had some scripts running on my home Mac to periodically write perspectives out to static HTML, but there were a couple bugs in OmniFocus that prevented it from working reliably 100% of the time.
