If he has a PC or an Amiga, he could use prlink for the task. I copied the PET version of prlink to the tape with a Commodore 128D and attached the same datassette to my 8032-SK to load the program. In that way, I didn't have to type in the loader program written in BASIC. If he can wait some weeks, he could use the datassette emulator I'm working on. Last night I learned that Linux has more common with the 6502 than I thought: its serial routines ignore the XON/XOFF or CTS/RTS handshake signals during writes, just like the 6502 ignores the RDY signal during writes. In order to avoid buffer overflows, I have to make write(2) system calls to the serial line in chunks less than half of the receiver buffer capacity. In that way, the handshake signal works reliably. Tonight I'm going to measure the pulses generated by the tape emulator with an oscilloscope. The VIC-20 didn't recognize them yesterday. It probably is just a programming error. The guy could perhaps use the tape emulator already in this early stage. The main function of this device will be to offer prlink-like functionality for RS-232 based systems. Ah, there's also a software-only solution if the guy has a sound card in the device he is using to access the Internet. In <URL:http://www.funet.fi/pub/cbm/crossplatform/transfer/datassette/>, there is e.g. a utility called WAV-PRG. It could be used to record Commodore programs to tape.
