In 3.3.5a has anyone found a possible way to read/write Binary from the server to the client?
For example, sending an image from the server to the client using AIO?

custom packets? might be a bit heavy for addon messages (aio), also might not support sending raw bytes because they'd be special characters or it'd be too long

That's where base64 encoding would come into play.

isn't there a character limit ? I guess you could add some header to split between messages tho

You can bypass character limits on WoW's client, as can be seen ^

I also exposed file open perms on the client, but I've yet to expose file write.
If I can expose file write perms on the client itself, I could just send rb from the server to the client and save.
But that is something I haven't yet exposed.
Only file open.

I have a mock system to "write" from the client.
But it sends the data back to the server where io is already readily available in Lua.
