Has the loggregator team considered using Gary's Burd's WebSocket
(http://godoc.org/github.com/garyburd/go-websocket/websocket) instead of
Go's built-in WebSocket library? Go's built-in library doesn't appear to
support ping/pong frames (which seems weird that a Google invented protocol
would have a half-baked implementation in a Google runtime...)

It seems kind of silly to do stuff like this
rather than using the WebSocket protocol's built-in mechanism for detecting
stale connections.

Forgive me if I sound like a whiner. I love Loggregator. I just keep
finding things in Loggregator that are done in a way that's easy with Go
but non-standard which causes more effort for those of us on more
established platforms.

I'm really close to having a fully functional Loggregator client in Java

There a few things that are bugging me so I thought I'd provide some

- I'm not very fond of the DIY padding. PKCS#7 is really really easy to
implement (since Go doesn't appear to support it.) Why not go with this
standard padding mechanism? Regardless, it works but it was a pain to
figure out and reimplement.
- The signature in the LogEnvelope only covers the LogMessage's message
field and not the entire LogMessage. This probably isn't a huge problem
since it would still be rather difficult to intercept a LogEnvelope but if
you did, you could emit the same message to any application masquerading as
coming from any source. It seems more secure, to apply the digital
signature to the entire LogMessage but again, not a big deal.
- The nonsecond time resolution in the timestamp seems a little over the
top but I don't anticipate being around on April 11, 2262 when it overflows
so I'm not too concerned. :)

I'll post a link to my client once it's ready.
