On today's PTR notes Blizzard has revealed that starting with Patch 10.1.5, you will be able to freely trade items and gold directly to any other character in your region!
No, you cannot buy your own auctions, but depending on what servers your chars are, you can mail stuff, even cross faction.
Check this: https://us.battle.net/support/en/article/14296, all servers that are listed as connected act as they were the same server, I have alliance chars on one server and horde on a different one, but they’re connected and I can freely mail gold and stuff between them.
Does that include your own characters?

Isn’t the restriction on realms mentioned in that support article exactly what’s being removed in 10.1.5?
Apparently not, but every other restriction still stands (trade, party, mail, guild)
