Jcl, to be honest that's a lot less than I'm expecting to be outputting (hopefully I'll be able to productise this in the long run).
That was just a simple example page. I would expect that your page size would be
a lot closer to the 2K-3K range rather than the 20K-30K range. If you start to
add images and graphs my estimate would be way off.
There shouldn't be any issue about using an SD card to store HTML though should there....?
I don't see any issues with using a SD card. IIRC there is an app-note and library
on the web.
Are there any other storage solutions available, e.g. increased EEPROM sizes?
You can increase EEPROM my changing an ATmega168 to an ATmega328.
You could also add an external EEPROM. If you are going to add an external
EEPROM I would use the SD card instead.
Using the SD card would give experience with that technology and easy expansion
options.
