If the modularEEG ICSP (in circuit serial programming) interface is changed from 
the SP12 compatible layout(*) to the Atmel STKxxx compatible layout, you have 
the choice to use the olimex serial programming cable (avr-pg1b.pdf) with 
PonyProg or the olimex parallel programming cable (avr-pg2b.pdf) with AVR ISP.

You even could modify the current SP12 compatible programming cable so that it 
is compatible with the Atmel STKxxx compatible layout and use the SP12 software.

How much delay do you get? I guess my delay is less than an hour.

(*)
In fact this layout was recommended in the document:"ATMEL AVR910 In-System 
Programming" (doc0943.pdf) on page 2 fig. 2

The original SP12 programmer does not use the 2x3 pin header contact at all.

"...
Figure 2. The Recommended In-System Programming Interface Connector Layout.

Figure 2 shows the connector used by all Atmel In-System
programmers to connect to the target system. The standard
connector supplied is a 2x3 pin header contact, with pin
spacing of 100 mils.

For some reason ATMEL seemingly has decided to change this recommended layout to 
the new one used in the STKxxx.
