@richard the dev's are aware of this issue and it's not an actual current problem but as you said it is a scalability problem and should be taken care as soon as possible...
From the top of my head, the better theoretical solution that was presented was a variable block size, although i am not sure in what feet do we stand regarding the fixing this issue since i am not a Wallet Dev, but i know there are more dev's working on the wallet now than ever was so i am sure someone will come up with a solution in a near future... ;D
