I just had an idea today (well yesterday in my time zone

) and wanted to know what you guys think and if it is possible. There is no dakkadakka mobile, but perhaps it can get a head start that when using a mobile phone/itouch/etc it remembers you logged in but still keeps you logged in on your non mobile computer? To me this seems simple and easy but i dont know anything about updating forums (or even a web site

).
Is this possible?
Do i not make any sense and need to rewrite?
