URLOpener opens multiple browser tabs

In my role I give a lot of presentations which involve demoing multiple sites in a browser.

To have all the URLs preloaded when I start the presentation, I’ve experimented with a number of tools:

1. Firefox session manager (works fine, but fiddly to transfer between PCs)

2. Firefox portable (fiddly and unreliable in our corporate network)

3. Delicious’ open in tabs feature having tagged the respective URLs accordingly (fiddly adding the extra tags)

4. On one particular day of IT failure simply opening a whole series of tabs and pasting the URLs in one by one. Ouch.

What I need is a painfully simple and reliable way of opening multiple tabs on any PC.

Step forward URLOpener. You simply paste in a list of URLs, click submit and it will open them as new tabs. Done.

Put any better ideas you may have in the comments section below.
