Fred meets Bob at the pub and shows off the latest app he's installed. Bob likes it and wants to have it on his phone, too. Q: What's the best way for Fred to help Bob install an application? Hint: On a Palm, Fred would just 'beam' the app to Bob's pda (we're assuming that it's a freely downloadable app, not requiring payment or registration). On an Android phone, can Fred somehow share it over Bluetooth, or display a QR Code for the app so that Bob can use his Barcode Scanner to get it from the Market (or slimeme.org, or wherever)? As far as I know, no file manager has a "display barcode" function (like Contacts does when you have Barcode Scanner installed), so I'm forced to describe the app, or go into the application list and dig out its "com.vendor.app" name. This seems decidedly un-slick.
