Viable MOBILE solutions for SMB with *?

as things are, is there a way to cut back mobile costs using asterisk? as long as there’s no wimax enabled mobiles in Europe, 't is gonna be taugh, but what could be done now?

thinking of something like IPDRUM (ipdrum.com/subpage.aspx?m=2&amid=748).

any crafty solutions of u geeks out there

or should just sit & wait for release of wimax chipsets rolling out :
