Any HN'ers happen to use Guacamole in order to gain access to Linux hosts (via SSH, of course) from an iPad? I'd be interested in hearing about how it works.

Any HN'ers happen to use Guacamole in order to gain access to Linux hosts (via SSH, of course) from an iPad? I'd be interested in hearing about how it works. Alternatively, I'd take recommendations for an SSH client for the iPad that supports public/private key pairs and connecting through a bastion/jumpbox/etc. (a.k.a. the "ProxyCommand" SSH client directive).
