Wow, Linaro. that’s a name I haven’t heard in a while. They were the ones to optimize Android builds during the IceCreamSandwich days and just last day I was wondering if there were any third party optimization project still out there. All the best to them.
pairdrop.net maybe?
It’s mainly for local network, but you can do internet transfers.
