Same end result, give or take. Different mechanism.

RSA keys can be encrypted via a fairly standard fashion that has nothing
to do with pgp or gpg. Openssl knows how to open such encrypted keys,
and so will a future version of rsyncrypto.

I think you meant LZMA. After spending a couple of minutes reading on
it, my gut feeling is that turning it rsyncable in any meaningful way
will greatly hurt the compression ratios you're used to seeing from it,
negating the reason you wanted to use it to begin with. It achieves
better compression ratios by having a very big lookback buffer (encoded
as a dictionary), which is the exact opposite of rsyncability.
