Some might have seen the message on CGTalk, i have not actually tested 
them yet but it looks like a nice collection of relatively high 
resolution skies:

Please excuse my ignorance. In what program can you open a .hdr file, and 
how is it used?

Megapov can use directly hdr files in a scene, as explained in section 
4.3 of Megapov's help file. If you just want to view hdr files, then 
HDRView will do the trick : http://athens.ict.usc.edu/FiatLux/hdrview/ . 
Also, the page http://athens.ict.usc.edu/Research/HDR/ is I believe a 
good starter about High Dynamic Range Images.

Hope this helps...

Are there any HDRI programs which supports saving in 48bpp png format?

Photoshop CS2, but that's rather expensive.

If you are looking for free software, I suppose you could use MegaPOV. A  
little cumbersome to use for converting image files, but it should be  
doable.

  I see no option for saving to png or to 48bpp format...

Christoph Hormann has a tool on his web-page called HCR-Edit, that might 
be what you're looking for : 
http://www-public.tu-bs.de:8080/~y0013390/hcredit/index.html

Can anyone tell me more about 48bpp png format ? Is it able to store 
float values ? What is its dynamic range ? It's not listed on 
http://www.anyhere.com/gward/hdrenc/hdr_encodings.html, a page I found 
extremely interesting about high dynamic range formats...

  Truecolor images usually store 8 bits per color component. Some
image formats, such as for example png, support also 16 bits per color
component (making a total of 48 bits per pixel).
