Same difference, but your approach will waste disc space unnecessarily.

It may work, but internal versioning and/or API changes may mean that the v7
API library won't be sufficiently backwards compatible with the v3 API
library, which is why John warned it may not work.

Why didn't you download iscan-2.29.2-1.usb0.1.ltdl7.i386.rpm or
iscan-2.29.2-1.usb0.1.ltdl7.x86_64.rpm from Epson's driver site, though?
The file name would suggest that it's compiled against the v7 API version of
libltdl rather than the v3 API version
(<http://download.ebz.epson.net/dsc/search/01/search/searchModule>, search
for v500, scroll down to the Perfection V500 scanner driver for Linux Ver
2.29.2/1.24.0 core package&data package, click download button). Found by
googling 'epson v500 sane' and following
<http://askubuntu.com/questions/11275/how-can-i-get-my-epson-v500-scanner-working>.
