I can't use aldiko on my phone so I'm not sure if it's possible.
Searched but couldn't find any information about linking ebooks from aldiko to a webpage. Only way that came close was to quote the whole book and then post it, which would probably be a ball ache.
I have a few other ebooks I can go through, then in November/December I'll get rid of this shitty Blackberry for an iphone or similar.
