dbeyer3069 has released Url2PSP, heres the details from his site:
<blockquote>This service is FREE and allows you to transfer URLs of files you would like to download to your PSP by entering them here. The PSP unit will connect to this web site, login using the MAC address of your PSP, transfer your list of desired file URLs and then download them.
The URLs you enter will be stored for up to 7 days in this website’s database. In the current version, you must remove the URLs from our database yourself, or wait for the system to purge them automatically after 7 days. In a future release, URL2PSP will automatically remove them for you. For simplicity and your privacy, we are asking for your MAC address instead of an email address.
NOTE: Although this web site only serves as a way to make downloading to the PSP easier and does not do any file transfers itself or store any files, please don’t use this service to aid in the downloading of any illegal or copyrighted materials. Your cooperation is appreciated.
To get started or to sign back in, please enter your MAC address. Your MAC address appears in the LOWER LEFT CORNER of the URL2PSP program screen as well as in the System Settings of the PSP.
Updates will be provided on a regular basis. Please check back for updated versions.</blockquote>
