Surely you can find a friend with internet who could download Reaper for you. Its' about an 11 MB file, so it doesn't take that long, and would fit on the smallest of flash drives.
How are you doing a podcast without internet access?
Alternatives would be a self contained recorder like the Zoom R16 or R24, Tascam DP24SC, Zoom H4n or H6, or Tascam DR40X. Most of them will come with recording software, like CubaseLE on CD. Most can be used as an audio interface, or as a stand alone unit. Choose based on how many channels you need at one time. IF you are doing performances, you can get either the Zoom LiveTrack L12 or Tascam Model 12. They are designed to act as live mixers but will also record multitrack onto SD cards.
I have a Zoom R24 that I have used for recording, hooked up headphones and mixed down to the SD card, and had a completed song. Pull the SD card and plug it into a computer and you can burn it to CD. I also have an old Yamaha AW1600 that can record 16 tracks and burn the final mix to CD. One mic, a pair of headphones and a few CDRs and you could put together a full recording, if you are work at it.
Like I said, there are lots of ways to record these days.
