AnthonyB alerted me to a bill that has just been introduced in congress that would change copyright law, in a manner that--depending on how certain terms are interpreted--could have implications for those of us who post recordings up on YouTube.
The important part of the proposed legislation is the section stating that 10 electronic public performances in 180 days constitutes a violation if it adds up to $2500 worth of total retail value somehow.
Whether this would affect us humble YouTubers much depends on how they're defining "retail value." Could a cover of me or Anthony playing an Einaudi piece be deemed to be worth, say, the 99 cents that iTunes would charge for a track? And if more than 2500 people watch it in 180 days (okay, maybe not likely for one of MY videos, but Anthony's garners that many views!

), that would seem to make it fall under the provisions of the new wording of the law.
I'm not sure that this law would change business as usual even if it were passed, as posting any recording of a piece that's not in the public domain is currently a violation of copyright law. And I'm thinking the primary targets of this legislation are those folks who take intact albums and upload them, track by track, as soon as they're released, not us Adult Beginners uploading our tortured renditions of pieces. I hope.

But I agreed with Anthony that it would be useful for people to know that this is on the radar.
For the truly curious, here's the text of the bill:
