I've "ported" the following packages to Maemo OS2008 (Chinook), and they run on my N810:

• qstardict
  A translating dictionary program. I like the interface better than sdict and the program has a very neat "popup" feature that does instant lookups of highlighted text from any program (web pages, documents, etc.). Command-line installation via tar file.
  
• otpCalc
  one-time-password calculator. Vital for secure logins using S/Key from untrusted machines (ie., an internet cafe). Based on the work from:
  http://linux.spiney.org/debian_linux_maemo_nokia_770
  with minor changes for the Chinook release of maemo. Command-line installation via tar file.
  
• ipqalc
  IP address range calculator for Qt. Command-line installation via tar file.
  
• RCS
  GNU revision control system. I couldn't manage any *nix system (including my tablet) without RCS. Command-line installation via tar file.
  
• diffutils
  GNU diff utilities. A prerequisite for RCS. Command-line installation via tar file.
  
• pinger
  GTK/curses multi-machine ARP and ICMP pinger. Complete ".deb" package available.
  
• units
  GNU command-line units conversion program. Based on the work from Peter Westerström. Complete ".deb" package available.
  
• kdepimpi
  Cross platform (Linux, Windows, Zaurus) PIM suite. The calendar program (kopi) is functional, and about 80% of the features work correctly. The other applications within the suite (contact list, mobile phone interface, time tracker) are less complete. With the attention of a developer and some publicity, this package has the potential to be a terrific PIM for the NIT. This port is available almost entirely due to the work of Michael Krelin. Command-line installation via tar file.
  
• gonvert
  graphical (Pygtk) units conversion package. http://www.unihedron.com/projects/gonvert/downloads/. I wrote a trivial shell script to install the program.
  

In most cases, the "porting" to OS2008 really just involved recompilation or a few minor updates for the new Hildon environment. Most of the credit should go to the original developers or people who did the initial port to earlier versions of Maemo.

I'm happy to make these executables available upon request (e-mail is preferred over private messages here) , but I don't have a permanent place to host the files. I'm really not a software developer, so I really want someone else to "take ownership" of the port, build a proper ".deb" installation package, and upload the package into one of the repositories so that it's publically accessible.

Please contact me directly if you want the executable or can help out in any way with making these applications into finished packages available for other users.
