I worked Yemen QRP SSB on 17m on 5/6/12 at 02:42 utc on 2nd call at home lucky....BUT the conditions have to be right your not going to do those everyday I also worked HK0 on 4 bands SSB QRP and all bands SSB except 6m QRO. I really enjoy QRP have 2 rigs at this time an IC-703 Plus with the W4RT duel filter setup and a Elecraft K2 recently upgraded to a 100w rig but still used mostly for QRP the 100w being for Field Day use.
It's all probigation always has been always will be. I work 2 nets a day one on 40m here in NA and one 20m for ZL,VK and of all places South Africa. A strange net for 3 areas but all on nightly here in US about 06:00-08:30 utc most nights. Keep up the QRP mobile contacts your doing great you might consider setting up some better antennas at home and having a go at some real DX there.
I run JT65HF daily QRP never over 5w and a lot of the time down to .5w. I check for probigation using WSPR and 2w a lot of the time when I'm in the shack using a vertical.
