What a great topic! I have two followup questions:

1. Would it be possible for somebody to imbed some important search keywords in the web page so that the search engines could see it after all? Like maybe in a comment, doc, or keyword tag?

The way I might do it is to just put a "text readable" title on the page; for example, "Wave Form Analysis Chart", then have a JPG of the PDF using my screen snapshot software (I like SnagIt).

That way, I would get the best of both worlds. But is that a good way?

2. How would you folks create an "embedded PDF" that is multi-paged?

For example, so that the person browsing the site would not have to click-wait-wait-wait for the whole file to be downloaded and opened by AcrobatReader, but instead, so that they could just grab the scroll bar and scroll? I know it's kind-of-sort-of like opening Acrobat Reader as a browser "plug-in", but it's really quite smooth and convenient. The following web sites/services already offer such a thing:

Quicken Bill Pay: I can view and scroll my invoices (for example, my phone bill, and my mortgage invoice) without actually downloading or "opening" the PDF files.

Turbo Tax: Allows me to look at my old tax returns from within my browser without downloading (and waiting for) them. I just click and scroll.

My Employer's 401k site: allows me to dynamically generate a PDF statement, containing or omitting items based on my selections. Similar to the bill pay and tax applications, this site seems to open a "PDF plug-in" reader. The whole "download and wait" step seems to be omitted.

So far, I don't "need" number 2 above for the site that I maintain; I'm just asking out of curiosity.
